[B.A.T.M.A.N.] [PATCH 08/10] batman-adv: free skb on TVLV parsing success

[Antonio Quartulli <antonio@meshcoding.com>]

From: Antonio Quartulli <antonio@open-mesh.com>

When the TVLV parsing routine succeed the skb is left
untouched thus leading to a memory leak.

Fix this by consuming the skb in case of success.
